The Cristero War, fought chiefly between 1926 and 1929, appears in corridos, religious songs, and musical memories from different regions of Mexico. These materials may express contrasting perspectives and may have been composed or recorded long after the events. A religious reference alone is not enough to attribute a piece to the conflict. This category locates documents associated with the war and its later remembrance. Authorship, place, date, and performance context should be identified where possible to distinguish contemporary testimony, later narrative reworkings, and present-day uses of repertoires linked to the period.
